ACT Potential Erosion Hazard Ratings for Hydrogeological Landscape Units

The dataset contains hazard ratings for land salinity, stream salt load, and stream EC, as well as overall salinity hazard for each Hydrogeological Landscape (HGL) unit in the Australian Capital Territory. It was captured at a 1:25,000 scale and includes information about landscape functions and salinity management strategies. The dataset was developed by Rob Muller, Wayne Cook, Allan Nicholson, and Alie Cowood and is hosted by the ACT Government Geospatial Data Catalogue.

Use Cases

• Assessing land salinity hazard ratings for Hydrogeological Landscape units
• Evaluating stream salt load and stream EC hazard ratings for water quality management
• Identifying appropriate salinity management strategies based on landscape function descriptions
• Integrating causative factors like geology, soils, slope, and climate for salinity risk modeling

Strengths

• Captured at a 1:25,000 scale, suitable for paddock-scale assessment
• Integrates multiple information sources including soil landscape maps, hydrogeological data, and salinity occurrence maps
• Provides hyperlinks to full management descriptions for each HGL unit

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The ACT Government disclaimer states the map may not be free from error
